CALL-BELL.

SPECIFICATION forming part of Letters Patent No. 225,690, dated March23, 1880.

Application filed September 11, 1879.

To all whom it may concern Be it known that I, JOHN P. OONNELL, ofKensington, in the county of Hartford and State of Connecticut, haveinvented an Improved Call-Bell, of which the following is a description,reference being had to the accompanyin g drawing, where the figure is aview of my improved call-bell in the position of being struck orsounded, and with a part of the sounding-shell represented as brokenaway,

. this to show the interior mechanism.

The letter a denotes a sounding-shell of the usual concavo-convex shape,having a reciprocating or up-and-down motion. This may be effected byhaving the shell bear the pintle or shaft 1), having suitable play in oron sockets borne by the standard 0, or by having such pintle or shaftstationary and having the shell slide thereon. The shell is heldnormally at the top of its play by the spring d.

On the standard is pivotally hung the hammer 6, one end of which isfurnished with a knob or ball for contact, in the act of sounding, withthe sounding-shell, the other end being formed into a tappet. When thesounding-shell is depressed, which is effected by pressure on the knoba, the inside of the shell bears down upon the tappet end of thehammer-arm and throws the ball on the other end out against the shell,causing it to sound. When said pressure is removed the spring returnsthe shell to its normal position.

While some of the features of this invention are usable whether or notthe hammer be borne within the mouth of the sounding-shell, there is aparticular fitness that in call-bells, which are largely used onfamily-tables, the hammer should be hung within or under the mouth ofthe sounding-shell, so as to wholly or partially conceal the hammer fromsight. tion with such a construction it is novel, so far as I know, tocombine either a movable or immovable hammer with a sounding shell whichis moved bodilyi. 0., the bell is moved as a whole, in contradistinctionfrom a bell swung on a shaft or axist0 meet the hammer in the act ofsounding the hell.

I claim as my invention- 1. In acall-bell, the combination of ahammer,hung within or under the mouth of the sounding-shell, with asounding-shell moved bodily to meet the hammer in the act of striking,all substantially as herein shown and described.

2. In acall-bell, the combination ofthe movable sounding-shell a, thepintle or shaft 1), the standard 0, the spring d, and the hammer c, allsubstantially as herein shown and described.
